A good game to get people talking together at the start of the party. Collect a set of pictures from places in your town, or famous locations (such as a beach in Hawaii or a famous statue), or people (both local and famous) and display them on the wall with a number. The guests have to identify them and write the name or location on a sheet of paper. When everyone is done, read off the answers and have everyone mark how many they got right. The winner is the one with the highest score.
